Answer:
95% Confidence interval: (14.4537 ,15.1463)
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 15 feet
Sample mean, = 14.8 feet
Sample size, n = 16
Alpha, α = 0.05
Sample standard deviation, σ = 0.65 feet
Degree of freedom = n - 1 = 15
95% Confidence interval:
Putting the values, we get,
is the required confidence interval for the true mean length of rods.
Mercury's distance = 5.8 x 10¹⁰
Venus' distance = 1.86 farther or more than Mercury's, namely 1.86(5.8 x 10¹⁰)
Earth's distance = 2.58 farther or more than Mercury's, namely 2.58(5.8 x 10¹⁰)
about how many meters farther is Earth's than Venus? well, we can simply get their difference, we know the Earth is farther than Venus, so we can just subtract Venus' distance from Earth's to get the difference, namely 149640000000 - 107880000000.
Answer:
(301)^2-(300)^2
it is in the form of
a^2-b^2=(a+b)(a-b)
so,
(301+300)(301-300)
(601)(1)=601
Answer:
30
Step-by-step explanation:
s_{n}=\frac{a+l}{2}=n
first term=a
last term=l
number of terms=n
1485=\frac{6+93}{2}n
99 n=1485×2=2970
n=2970/99=270/9=30
number of terms=30
